In T3/T4 stage gastric cancer, XCL2, CXCL4, CX3CL1, CCL8, CCL5, CCL3, and CCL25 were correlated with effector memory CD4 T cell, and IL2, IL3, IL12A, IL12B, IL15, IL17C, IL17D, IL18, IL19, IL20, IL22, IL26, IL27, and IL31 were associated with the above correlations (Figure 5(a), Table S7). This evidence concerns the gene CX3CL1 and gastric cancer.
